General Description

TRI-P-TOLYLCHLOROTIN, also known as TPTC, is a chemical compound consisting of a tin atom bonded to three p-tolyl groups and a chlorine atom. It is primarily used as a fungicide and is known for its antifungal properties, particularly in the treatment and prevention of wood decay in buildings. TPTC is also used in agriculture to control mold and mildew on crops and in industrial applications such as the preservation of wood and textiles. However, TPTC has been the subject of controversy due to its potential environmental and health hazards, with some studies suggesting it may be toxic to aquatic life and harmful if inhaled or ingested by humans. As a result, the use of TPTC has been restricted or banned in some countries.

Organotin esters of 3-ureidopropionic acid. Crystal structure of triphenyltin(IV) 3-ureidopropionate, (C6H5)3SnOCO(CH2)2NHCONH2

Syntheses and spectroscopic (119mSn Moessbauer and infrared) data are reported for tiorganotin derivatives of 3-ureidopropionic acid of the general formula.R3SnOCOCH2CH2NHCONH2 (R = Ph, nBu, cyclohexyl, and p-tolyl) and Ph2RSnOCOCH2CH2NHCONH2 (R = nBu, p-ClC6H4 and cyclopentyl).The crystal structure of triphenyltin 3-ureidopropionate has been determined.The compound adopts a trans-C3SnO2 trigonal bipyramidal geometry with the axial positions occupied by the ester oxygen and the ureido-oxygen of an adjacent molecule.The polymer units are held together by intermolecular hydrogen bonding between the group NH of the ureido fragment and the oxygen of the carboxylate carbonyl.
